sPEcIFrcA'rIoN forming part of Letters Patent No. 634,237, dated october3, 1899. Application filed February 18,1899. Serial No. 705,997. (Nomodel.)

T0 @ZZ whom, it may concern.-

Be it known that I, GODFEEY FUGMAN, a resident of Cleveland, county ofCuyahoga, and State of Ohio, have invented certain new and usefulImprovements in Metallic Sheets or Bodies for Usein the Construction ofBuildings, dto.; and I do hereby declare the following to be a full,clear, and exact description of the invention, such .as will enableothers skilled in the art to which it pertains to make and use the same.

My invention relates to improvements in a metallic body for floors andwalls of buildings.

The primary object of the invention is to provide a metallic sheet orbody that is more especially designed for fireproof construction and forthe formation of the body portion of cement or plaster for walls oriloors of buildings and that comprises a construction that is simple anddurable and is not shrunk or shortened, expanded or enlarged, orweakened during the process of manufacture and is capable of addingmaterially to the strength of the Walls or floors.4

With this object in view and to the end of realizingother advantageshereinafter appearing the invention consists in features of constructionhereinafter described, and pointed out in the claims. Y

In the accompanying drawings, Figure I is a plan of a slitted metallicsheet employed in forming my improved metallic body. Fig. II is a planshowing the metallic body that is formed from t-he sheet illustrated inFig. I.l Fig. III is an end elevation of the body. Fig. IV is a sectionon any one of lines IV IV, Fig. II, looking in the direction of thearrow, and shows only the portion of the body through which the sectionis taken. Fig. V is a section on line V V, Fig. II, looking in thedirection of the arrow, and showsonly the portion of the body throughwhich the said section is take-n.

My improved metallic body, that, as already indicated, is moreespecially designed for use in plaster-work or cement-work, is made froma metallic sheet (shown in Fig. I) and provided with any suitable numberof rows of preferably parallel slits a, extending transversely of therespective row and having opposite end portions of the slits convergingtoward the central portion of the slitthat is, each slit has divergingportions between its central portion and end extremities. In the caseillustrated the sheet is provided with three parallel rows of slits, andthe slits of each row of slits are parallel. The rows of slits arearranged a short distance apart,l

so as to leave a plain and unslitted portion between adjacent rows ofslits, and the outer rows of slits are separated a suitable distancefrom the adjacent side edge of the sheet, s0 as to leave the sheet plainandunslitted next to the said edge. The portions of the sheet betweenadjacent slits of each row of slits is bent laterally in any approvedmanner, so as to form a wing I), projecting laterally from the sheet,and the portions between the slits of each row of slits are bent,preferably, alternately in opposite directions, so as to form two rowsof wings upon opposite sides, respectively, of the sheet and so that thewings of each of the said rows shallalternate with the wings of theother row. It will be observed, therefore, that by slitting the sheet asaforesaid and then laterally bending the sheets portions between theslits in the mauner hereinbefore indicated rows of wings are formed uponeach side of the sheet, that the wings of each row of wings are paralleland arranged a suitable distance apart, and that the wings of each rowof wings upon one side ofthe sheet alternate with the wings of theopposite row of wings upon the other side of the sheet. I would remarkalso that the wings of each row of wings upon each side of the sheet arearranged, preferably, so as to alternate with the wings of the adjacentrow or rows of wings upon the same side of the sheet, and in the caseillustrated, therefore, the wings of the central row of wings (shownvery clearly in Fig. V) at each side of the sheet alternate with thewings of the outer rows (shown very clearly in Fig. IV) upon the saidside of the sheet.

The slitting and bending of the sheets portions between the slits in themanner hereinbefore described form, of course, apertures c in the sheetbetween the wings b, and the said IOO apertures accommodate thereception and In using my improved metallic sheet or body in wallconstruction I would remark that the sheet or body would be run fromdoor to door and attached to the door-supports in any approved mannerand supported, furthermore, by metallic posts or studding made ofangle-iron or other metallic forms.

Vhat I claim is- 1. As an article of manufacture, a metallic sheetprovided with rows of slits, and having the portions of the slitsbetween the latters ends and central portion diverging from the centralportion so that the portions of the sheet between two adjacent slits ofa row of slits can be bent laterally to form a laterallyprojecting wing.

2. A metallic sheet provided with parallel rows of slits and having theslits of each row Signed by me, at Cleveland, Ohio, this 16th 3o day ofFebruary, lSQ).
